Question w203 220cdi 2002 horrible idle

Hi
my c 220 cdi went in to limp mode, total power loss and max 3000 rpm. did a diagnose and found air flow mass meter error. changed air flow mass meter. now the engine revs over 3000 rpm, but its idle is horrible, and a light touch on the trottle makes it even more horrible.

What code errors are you getting now? Sounds like you still are having misfires. Could be fowled plugs or a bad coil

My 2007 220 CDI is a diesel i.e Common Rail Direct/Diesel ? Injection.

Does the idle improve with the air flow meter disconnected ? If this is so you may have the incorrect flow meter.
